@lioness, we have had similar issues with our local Walmart stores. There are 4 close by and NONE have had most of what we need. Target is the store that we have had the most success with. They have a published self limiting campaign in our local stores to prevent hoarding so that has had a positive effect on availability. I'm sure there are more Walmarts around than Target stores, but guess where I'll continue to shop even more? Capitalism is great, but not at the expense of others who need supplies and food to just survive. Good luck to all. We even cancelled our Walmart pharmacy needs in favor of a CVS located in our favorite Target store. It is not too busy like the Walmarts so exposure is also more limited for safety of all high risk patients.
Take care!
